I am fairly new to the VoIP movement so please treat me as a 4 year old in pre-k. I am interested in better understanding what kind of hardware we are missing in my enviroment to go wit a VoIP (SIP based phones) solution.
We have 7 locations, with 6 Full T1 point2points coming into my main location.
At the main location we have our internet router
Cisco 1751, a pix515 firewall, then we have a 3725 routers (this is the router where all trafic gets routed to, all 6 locations)
at each remote location we have cisco 1721 routers
and all our switches are cisco catalyst
We are looking to go with a Cisco Call Manager solution but interested in know if my hardware is capable of handling the load of VoIP on my network. thanks for your answers
